No, there are several arguments for the after turbo installation... if you would read the posts. Also, there is an argument there that "why does *cylinder 3* (#1 in the DSM case) run the hottest?" Do you really think it's struggeling for fuel? I doubt it. Every car is different, and I bet that every car's runner can vary in temps from what's the leanest, to whats the coolest. As far as external factors are conserned, you could make the same argument about the manifold too, however, I tend to think once the engine is warm, external factors wont cause a change in temp readings. Besides, the EGT is reading GAS tempretures, not o2 (up-pipe) housing temps. Plus, you should never TUNE with your EGT, a dattalogger is the choice here. And EGT is just a device for you to monitor while unleashing your car on the freeway, and make sure everything is reading NORMAL. If temps DO rise, in any of the runners, you'll be able to tell in your overall egt readings.

However, it seems that steve got the autometer, so *if* he does choose to install it in one of the runners and he's at WOT on the freeway with the EGT pegged at 1600*, how's he supposed to know what his ACTUAL temps are. He could be running 1800*? :?
